Hello Friends C programming language is called mother language of any programming language if you learn concepts in c that concepts help you to learn other languages easily.Today i am teaching you whats is the exact differencebetween-void main()-int main()Before getting the difference between both function first learn how main() function work

1)main() -Every programs in c start with main function. -after writing the c code we need to compile it (Compile means we can find some compile time error which are some syntax error missing parenthesis,Or our Typing mistakes called compile time error) -Note that our compiler don't show the run time error. -After Successfully completion of compiler without error we need to execute our c programs. -When we Run our c program operating system have control on it its will find out the main function in programs and start doing execution of our written code

2)void main()

-According to old ANSI C standard we are using void main(). -If we don't need any return value we use return type 'void' -And Notice that when we using void main() we don't return any statement in the main block to return the content to operating system

Syntax

Code:

void main(){

printf("Hello Protutr");

}

-Here is the one problem that void doesn't return any value then our operating system do not get any acknowledge to that our C program successfully completed or not so Operating a system confused that and you got such situation where when you running a c program then sometime its crashed. -and we are using here void so we doesn't have any way to say operating system that our programs crashed at this moment -So try to ignore using void main()

3)int main()

-int main() function return a integer value after function completion that is zero(0) or Non-Zero Value. -You already notice that when you are using int main() then we use return 0;statementSyntax:

-return 0 ->if our operating system reach at this stage then they got acknowledge that completion of the running programsreturn nonzero->if operating system doesn't reach at the return 0; statement then non zero value shared to operating system means that programs got stuck at some place

-So Use int main() instead of using void main(); this is suggested answer
